Augustine Answers Pelagius Pt 3

Pelagius taught that man was perfectly holy and in no need of God's special aid. He taught that man was perfect and sinless.
Augustine argued from Scripture that even Job was not truly blameless. But that even Job had to look to another, that is Christ, for salvation.
Augustine further proved that Perfection is not in man.
‎For these are God’s words concerning him: “Hast thou diligently considered my servant Job? For there is none like him on the earth, blameless, righteous, a true worshipper of God, who keeps himself from every evil work.” First, he is here praised for his excellence in comparison with all men on earth. He therefore excelled all who were at that time able to be righteous upon earth; and yet, because of this superiority over others in righteousness, he was not therefore altogether without sin. He is next said to be “blameless”—no one could fairly bring an accusation against him in respect of his life; “righteous”—he had advanced so greatly in moral probity, that no man could be mentioned on a par with him; “a true worshipper of God”—because he was a sincere and humble confessor of his own sins; “who keeps himself from every evil work”—it would have been wonderful if this had extended to every evil word and thought.
Pelagius argues from the idea of sinless perfection.
“Well, but,” they say, “the Lord says, ‘Be ye perfect even as your Father which is in heaven is perfect,—an injunction which He would not have given, if He had known that what He enjoined was impracticable.”
